Kimihito’s been sent to work on a farm! He gets up at dawn, dresses in overalls, and works with his hands. But just what kind of work are those hands doing? After all, this is no ordinary farm--all the other farm workers are sexy, buxom monster girls…and the livestock isn’t the only thing that needs milking.

A whole new group of sexy monster girls are chasing after Kimihito, and they're all hungry for his blood! While he goes undercover to try and find the third "rogue liminal," Kimihito soon finds himself at the mercy of their voracious blood-sucking appetites. Can Miia, Papi, and the rest of Kimihito's menagerie find him before he's drained completely dry...or meets a fate worse than death? This romantic harem comedy is sure to get your heart pumping!

So far, Kimihito's been lucky. The monster girls living with him have been cute, curvaceous, and have never tried to kill him on purpose. But now, the dark side of liminals rises to the surface. Piggish orcs run hog-wild over Japan to satisfy their perverted desires. And the team that the government assembles to combat them is every bit as strange and inhuman as the criminals they're fighting. Meanwhile, Kimihito has to contend with adding the lovely and elegant mermaid Mero to his ever-growing menagerie of monster girls. How will the possessive Miia, the noble Centorea, the bird-brained Papi, and the slime-girl Suu react to the newest addition to their household - and yet another contender for Kimihito's heart?

In a shocking twist (okay, maybe not so shocking...), Kimihito learns that he's been playing host to a princess! Mero the mermaid is actually the daughter of the king and queen of the sea, and now her royal mother is summoning her back home. Kimihito, along with the other monster girls living in his household, go to visit the mermaid queen in the hopes of changing her mind. Along the way, they uncover a tangled scheme that involves kidnapping, royal intrigue, tragedy, and, of course, naughty tentacles. If this intrepid group can manage to stay un-molested long enough to solve the mystery, they could transform the entire mermaid kingdom! But for once, Kimihito isn't the only one risking his life in the name of interspecies relations.

Kimihito's eyes are about to pop. The mothers of not one, not two, but three of the monster girls who live with him are coming for a visit. It doesn't help that this trio of mothers is every bit of sexy as their daughters - and just as dangerous to Kimihito's mental and physical well-being. Stuck in the middle between the mothers and their daughters, Kimihito learns more than he ever wanted to know about the mating habits of lamia, harpies, and centaurs, while repeatedly facing the possibility of an ecstatically painful death. Fur, feathers, and scales are about to fly, as Kimihito's hide hangs in the balance!

Get married and I kill you. This was the letter sent to Kimihito, an ordinary guy living with a houseful of extraordinary beauties, by a mysterious writer known only as "D." Now it's up to Interspecies Coordinator Smith, Kimihito, and his ever-increasing menagerie of monster girls to find out who is behind the threatening letter before it's too late. The game plan? Use Kimihito as bait by sending him on a series of dates with monster girls. Along the way, several possible suspects emerge, each of whom has a "D" connection of one kind or another. Meanwhile, Kimihito's potential brides each begin acting strangely. Are they taking the fake dates too seriously - or is something (or someone) far more sinister at work?

When the members of the MON get suspended for accidentally zombifying a young girl (with an assist from Lala), Kimihito tries to console them by spending a full day on a date with each individual member. Not surprisingly, every date ends in its own unique flavor of disaster. From dodging ghost marriages to picnics gone wrong, Kimihito will be very glad indeed when MON’s suspension is over! Meanwhile, Draco learns a lesson in humility while trying to win back Miia’s favor. It’s more chaos and comedy in this MON-focused volume of everybody’s favorite monster girl series!

What do world governments do when they learn that fantastical beings are not merely fiction, but flesh and blood-not to mention feather, hoof, and fang? Why, they create new regulations, of course, like the Interspecies Cultural Exchange Accord! When twenty-something Kurusu Kimihito becomes an involuntary "volunteer" in the government homestay program for monster girls, his world is turned upside down. A lamia named Miia is sent to live with him, and it's Kimihito's job to make sure the sexy snake girl integrates into everyday life. While cold-blooded Miia is hot for Kimihito, the penalties for interspecies breeding are dire. Even worse, when a buxom centaur girl, and a scantily-clad harpy move into Kimihito's house, what's a full-blooded young man with raging hormones to do?

What happens when Miia and Centorea decide to become working (monster) girls? They want part-time jobs to help pay Kimihito back for their living expenses, but it's harder than they expect for a lamia and a centaur to find work in a city built for humans. Miia and Centorea must endure rejection, humiliation, and job offers no descent girl would ever accept on the way to finding that perfect part-time job. Meanwhile, three rogue liminals have come into the country illegally--and they're all after Kimihito! Now, on top of his normal, everyday peril, he has to worry about being attacked by mysterious, unfamiliar monster girls who are "seriously bad news." Poisoned, drugged, drowned and seduced--Kimihito will need all the help he can get if he wants to survive with his bones and virtue intact!
